Abstract (en)

A rotary electric machine (100, 100A) in an arrangement includes a stator (120), and a rotor (130) capable of rotating around a rotation center. The rotor (130) includes a first rotor core (132), a second rotor core (133), and a magnet (131). The first rotor core (132) includes first rotor magnetic poles (134) that are arranged being spaced apart from one another in a circumferential direction and that face first stator magnetic poles (123), and is annular. The second rotor core (133) includes second rotor magnetic poles (135) that are arranged being spaced apart from one another in the circumferential direction and that face second stator magnetic poles (124), and is annular. The magnet (131) is located between the first rotor core (132) and the second rotor core (133) and provided with a slit-like magnet separation portion (136) that separates at least a part thereof in the circumferential direction, and is annular.
